Specification of Letters Patent.

Patented March 3, 1908.

Application filed April 12, 1907. Serial No. 367,761.

To all whom it may concern:

Be it known that I, FREDERICK C. BLANCH- ARD, a citizen of the United States, and resident of Bridgeport,l in the county of Fairfield and State of Connecticut, have invented new and useful Improvements in Lavatory- Basins, of which the following is a specification.

My invention relates to the construction of lavatory basins and like apparatus and consists in sundry mechanical improvements whereby such apparatus is rendered simple in operation, sanitary, and convenient.

In the drawings hereto annexed, which illustrate an embodiment of my invention: Figure l is a front-to-back vertical section of a lavatory bowl showing the manner in which it is mounted and operated. Fig. 2 is a detail showing one of the supporting and guiding brackets. Fig. 4 is a top view of the same, and Fig. 5 is a side-to-side vertical section.

A. A. are a pair of standards or frame members, preferably composed of cast iron, and adapted to serve as supports both for the basins and for water supply' pipes S. S. A waste trough F is mounted below the pipes S. S. In practice these standards are preferably duplicated, as shown, so that a double row of basins may be supported thereon.

The basin supports are brackets C, wherein are formed, preferably in the casting, the sevmental guides E. These guides are circulai? and subtend an arc sufliciently long to provide for tipping the bowl or basin. In

the form shown in the drawings the segmental guides E are slots, which coperate with a two point bearing on the bowl. The bowl B is supported by and between two brackets O, and is preferably made of enameled cast iron. A ledge G, extends around the bowl B, and on the side flanges of this ledge are formed the segmental lugs D, which have a loose sliding fit in the segmental guides E. These segmental lugs are preferably squared at their ends; these ends d d2 are'the essential portions of the lugs, which at d and d2 furnish two point bearings in the segmental guides E.

In respect to the mere rocking or tipping movement of the bowl B on the bracket C, these segment-guides and supporting bearings are in part mechanically equivalent to a Fig. 3 1s a side view of a bowl..

simple trunnion and journal, but in other respects the guides and bearings perform useful functions of which the trunnion arrangement is incapable.

Lavatory basins of the character herein described are designed particularly for use in factory washrooms, or in other places where the users thereof are for the most part careless and often mischievous, in handling the apparatus provided for them.

lt has been observed that trunnion-carried basins are often abruptly and violently tipped, so that part of their contents is slopped on the licor or on bystanders. Mischievously inclined workmen will frequently reach from one side of a double row of basins and tip up a basin suddenly, for the sake of discomfiting the person using it. In situa tions such as those referred to, it has been found advisable to employ tipping bowls, rather than stationary bowls with the consequent small waste-pipes, plugs and chains, for the reason that tipping bowls which deliver waste to an ample trough are simpler, less liable to be put out of operative condition, and more sanitary, than stationary bowls.

My improvements herein described conserve all the advantages due to the tipping bowl construction, and eliminate its disadvantages. If for instance the user should attempt to tip the bowl B abruptly from its horizontal position to the dotted line position shown in Fig. l, either byan upward or an inward push, the lug D, by means of its two point bearing on the segment guide E, instantly acts as a clutch, and arrests the movement of the bowl. Only a gentle push can be effective to tip the bowl and spill its contents, and a gentle movement is what is desired. Any attempt to tip the bowl in the opposite direction outward from the horizontal position, will be equally frustrated because the end of the segmental guides serves as a stop against such movement.

The spill opening of the bowl B is at the rear provided with the roll-over lip H. The ledge G terminates at the rear side of the bowl in a downwardly depending and preferably thin edged fiange g which joins with the roll-over lip II, which'terminates in a depending edge h When the contents of the bowl exactly A ECTICUT, ASSIGNOR TO THE ASHCROFT ONNECTICUT, A CORPORATION OF CON- B have been spilled into the waste trough F, soine remainder of the liquid contents will inevitably cling to the surfaces of the bowl and ledge, these however, will gather in drops on the flange g and run therefrom to the depending edge i. On returning bowl B to horizontal position, the drippings from the anges g either fall directly into the waste trough or travel to the roll-over lip H, and thence drip from its edge 7i into the trough F, instead of running down the under side of the bowl and thence to the floor. In practice the standards A will be cast with bowl Supports on each side, so that a battery of bowls can be set up in a double row, and be enlarged at will by the addition of other similar standards and bowls. The bowls are set in place as the standards are set up, and thereafter are irrernovably secured.

What I claim and desire to secure by LetL 2@ ters Patent is:

1. The combination of standards, a bowl supported thereon, one of the two said menibers provided with curved segment guides the other with two-point bearings coacting 25 with the segment guides.

2. The combination of standards, a bowl FREDERICK C. BLACHARD l/Vitnesses:
